The world is getting crazy. Last time I checked something related I found
out, there is now MTP and PTP - media and picture transfer protocols. Some
newer cameras (see post from 2006 [1] do this as well and you have to tell
it in which mode it should present itself when attached via usb.

On our new camera I configured few years ago mass storage and never
bothered, but recently I had to learn that there is something I was not
aware of for many years :)
Modern mobile phones are even worse as they incorporate many devices and you
have only 1 usb plug on it :)
